What fuel pump are you guys using for MPI 43PSI, 60lb injectors, about 650 HP. Found a lot of options out there but not many marine USCG rated. Don't want to overkill it with a high current model.

Are you using this one? I was actually debating on this same model.

Yes, I bought 2 for my Holley EFI project. I just dyno'd the other weekend. At full load 584 HP maybe 1PSI variance.

I have always used Weldon 1100-A. Not sure if they are USCG approved, but they sure work well.

I run Aeromotive A-1000 marine pump

What's the lift on this pump? I wouldn't want to mount it to low in the bilge.

Pretty sure I am going with this pump. Going to run -10 AN in and -8 AN out to the filter. What did you use for mounting?

I don't know the lift. But friend just mounted 2 to near top on outboard stringers and it worked just fine.
I use the 60mm for pump and 50mm for filter.
